It looks like the placeholder text (for the existing name of the file) is the same color as the actual text. I thought something was messed up in that I could not select or highlight the text.
It is currently a slightly lighter grey than the actual text color, but not a huge contrast.
I think the biggest usability improvement would be to seed the input value with the existing name as opposed to making it the placeholder text, so that it can be modified.
An alternative improvement would be to increase the contrast by making the placeholder text more clearly a placeholder and thus lighter.
